Legionella antibodies in human and animal populations in Kenya.
Using a microagglutination method, domestic and wild animal sera, together with human patient and healthy blood donor sera, have been analysed for titres against various Legionella species, comprising fourteen different serogroups. Generally, the level of moderately elevated titres, i.e. greater than or equal to 64, was low for all the aforementioned serum groups. Within the domesticated animals, cattle, pigs and dogs presented a much lower prevalence in Kenya than found elsewhere, whereas it was the other way round for goats. Human sera, either from patients or from healthy donors, did not react against L. pneumophila serogroups 1, 6, or 3, which in that sequence are the most common L. pneumophila serogroups in Europe, and in other geographic areas where legionellosis is common. High titres of greater than or equal to 256 against L. pneumophila serogroup 6 (two cattle) or against L. bozemanii strain Mi-15 (two cattle, one dog) indicate that although the epidemiological picture may be different from other parts of the world, Legionella infections exist in Kenya as well.
